SCons 0.13 is now available

SCons alpha release 0.12 is now available for download. SCons is a software construction tool (build tool, or substitute for Make) implemented in Python, based on the winning design in the Software Carpentry build tool competition (in turn based on the Cons build tool).

Release 0.13 contains an important fix for a critical bug found shortly after SCons version 0.12 was released.

SCons version 0.12 has a bug that occurs when a build directory is used without duplicating source files in the build tree ("BuildDir(duplicate=0)") and any subsidiary SConscript file includes another SConscript file.

This bug has been fixed in version 0.13, and a test has been added to the regression test base to catch this situation in the future.

Release 0.13 also contains an unrelated fix to support fetching files using earlier versions of Perforce that don't use the Windows registry.
